Matt Cutts heads up the Web Spam team at Gooooogle. He was interviewed yesterday and confirmed there is some loss of Pagerank on 301 Redirects. How much is some? Only Google knows, I guess. Full interview here - Eric Enge interviews Matt Cutts

    LOL ... If he says so, I really no desire to go read that but ... If that was true then many sites running SSL, ShortUrl Redirects, and etc would be hurt and that even includes google's beloved spam site twitter ...

    C'mon James! Matt said it, it HAS to be 100% true.

    Matt should lump all of his presentations and posts together and call it 1000 things you can do to make Google's job easier.

      well not much of a reason to get too excited.

      i mean it seems fairly obvious to me that there would at least be *some* decay.

      I mean decay after hopping has been part of the pagerank algo since its invention.

      This really only mostly matters for people who dont understand that there is a difference between www and non-www backlinks.



      Eric Enge: Let's talk a little bit about the impact on PageRank, crawling and indexing of some of the basic tools out there. Let's start with our favorite 301 Redirects.
      Matt Cutts: Typically, the 301 Redirect would pass PageRank. It can be a very useful tool to migrate between pages on a site, or even migrate between sites. Lots of people use it, and it seems to work relatively well, as its effects go into place pretty quickly. I used it myself when I tried going from mattcutts.com to dullest.com, and that transition went perfectly well. My own testing has shown that it's been pretty successful. In fact, if you do site:dullest.com right now, I don't get any pages. All the pages have migrated from dullest.com over to mattcutts.com. At least for me, the 301 does work the way that I would expect it to. All the pages of interest make it over to the new site if you are doing a page by page migration, so it can be a powerful tool in your arsenal.
      Eric Enge: Let's say you move from one domain to another and you write yourself a nice little statement that basically instructs the search engine and, any user agent on how to remap from one domain to the other. In a scenario like this, is there some loss in PageRank that can take place simply because the user who originally implemented a link to the site didn't link to it on the new domain?
      Matt Cutts: That's a good question, and I am not 100 percent sure about the answer. I can certainly see how there could be some loss of PageRank. I am not 100 percent sure whether the crawling and indexing team has implemented that sort of natural PageRank decay, so I will have to go and check on that specific case. (Note: in a follow on email, Matt confirmed that this is in fact the case. There is some loss of PR through a 301).
